Fluorescence decay times of anthracene and naphthacene doped crystals were also observed by a pulsive method and the probabilities of energy transfer from singlet excitons to doped acceptors were observed. The probabilities of energy transfer were analyzed with a model that diffusing excitons transfer their energy to acceptors by dipole-dipole interactions. From the temperature dependence of the probabilities the diffusion coefficient <I>D</I> of an exciton was determined as<BR>1⁄<I>D</I>=1⁄α′<I>T</I><SUP>−1⁄2</SUP>+1⁄β<I>T</I><SUP>1⁄2</SUP>{exp(<I>h</I>ν⁄<I>kT</I>)−1},<BR> where ν is the frequency of the longitudinal optical phonon. This result means that the transport effective mass of exciton is constant in the exciton band of a naphthalene crystal. Above 250 K, the temperature dependence of energy transfer was analyzed with a thermal activation process of the excited acceptor by an exciton."}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1410282679171220992","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000254127171"}],"foaf:name":[{"@language":"en","@value":"Uchida Kenji"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Department of Applied Physics, Osaka City University"}]},{"@id":"https://cir.nii.ac.jp/crid/1410282679171220993","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000254127172"},{"@type":"NRID","@value":"9000401833807"}],"foaf:name":[{"@language":"en","@value":"Tomura Masao"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Department of Applied Physics, Osaka City University"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00319015"},{"@type":"LISSN","@value":"00319015"},{"@type":"EISSN","@value":"13474073"},{"@type":"NDL_BIB_ID","@value":"000000118709"},{"@type":"ISSN","@value":"00319015"},{"@type":"NCID","@value":"AA00704814"}],"prism:publicationName":[{"@language":"en","@value":"Journal of the Physical Society of Japan"},{"@language":"ja","@value":"Ｊｏｕｒｎａｌ　ｏｆ　ｔｈｅ　Ｐｈｙｓｉｃａｌ　Ｓｏｃｉｅｔｙ　ｏｆ　Ｊａｐａｎ"},{"@language":"en","@value":"JOURNAL OF THE PHYSICAL SOCIETY OF JAPAN"},{"@language":"en","@value":"JPSJ"},{"@language":"ja","@value":"ＪＰＳＪ"}],"dc:publisher":[{"@language":"en","@value":"THE PHYSICAL SOCIETY OF JAPAN"},{"@language":"ja","@value":"一般社団法人 日本物理学会"}],"prism:publicationDate":"1974","prism:volume":"36","prism:number":"5","prism:startingPage":"1358","prism:endingPage":"1364"},"reviewed":"false","url":[{"@id":"http://id.ndl.go.jp/bib/7669512"},{"@id":"https://ndlsearch.ndl.go.jp/books/R000000004-I7669512"},{"@id":"http://journals.jps.jp/doi/pdf/10.1143/JPSJ.36.1358"}],"availableAt":"1974","foaf:topic":[{"@id":"https://cir.nii.ac.jp/all?q=General%20Physics%20and%20Astronomy","dc:title":"General Physics and Astronomy"}],"relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360011146135693696","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"Raman Scattering from Molecular Crystals.
